Unable to input data after getting an error message in module pool programming.

[former_member806437]

Hi,

My requirement is in module pool programming when the wrong input is given it has to display an error message and allow to give the correct input again.

But when I give the wrong input it is not allowing me to give the input . The fields are getting greyed out.

Please provide a solution to resolve this.

Thanks.

Please provide your code The message statement.

However, try this

MESSAGE 'Your Message .!' TYPE 'W' DISPLAY LIKE 'E'.
LEAVE TO SCREEN sy-dynnr.

or 

MESSAGE 'Your Message !' TYPE 'S' DISPLAY LIKE 'E'.

Hi,

To make all the fields ready for Input, even if a single field was entered wrongly.

Write code in PAI.

CHAIN.

fields: f1, f2, f3.

module < mod Name>.

endchain.

Hi,

In PAI the logic is generated by default. So do I need to add this the logic again.

[anujawani2426]

Hi,

If logic is same and it is already there then no need add it again.

Hello kunimbedu30

Use CHAIN.....ENDCHAIN

In PAI

CHAIN.

fields : field1, field2 MODULE validate_field.

ENDCHAIN.

and In program

MODULE validate_field.

"write validation in this area and give error message here

ENDMODULE.

Note : for more detail please check F1 help on CHAIN keyword, you will get detail idea.

Thanks

I don't recommend this trick:

MESSAGE 'Your Message .!' TYPE 'W' DISPLAY LIKE 'E'.
LEAVE TO SCREEN sy-dynnr.
or 
MESSAGE 'Your Message !' TYPE 'S' DISPLAY LIKE 'E'.

The right way to do was already answered, is to define a CHAIN FIELDS ... MODULE pai_module... ENDCHAIN in the PAI, with the list of fields that need to be input, and define:

MODULE pai_module INPUT.
  IF <some condition>.
    MESSAGE 'Your Message' TYPE 'E'.
  ENDIF.
ENDMODULE.
